Windows Server 2003 SMTP constantly active

We have a Windows Server 2003 running Exchange Server - it is configured to use the POP3 connector (every 15 minutes) to retrieve emails from a remote server.

I have noticed that there appears to be a constant stream of data being sent across the LAN (?), which stops as soon as I stop the SMTP service.

I have never noticed this before - is it normal behaviour or could something "bad" be going on?

Single server or multiple?
Have you indentified where the SMTP traffic is going?

If something was amiss (ie server being abused) then it would show in the logs. Fairly constant SMTP traffic isn't unusual, as spammers are always probing away at systems.

We have a local "office" server which runs Exchange Server, we also have a Web Server that provides mail server services to our clients - we also use this. The local Exchange server gets emails from the Web / Mail server via the POP3 connector. Outgoing mails go directly (I think!!).

Are there tools available to examine what the SMTP service is doing?

You can enable logging on the SMTP service.
This will give you all the information about the message being sent/received by your server.
